Problems solved by technology

[0004] Yet the heat collecting case cover glass of the solar heat collector of prior art is single-layer plate glass, and described single-layer case cover glass, because its surface area is larger, and its ability to block heat conduction and heat radiation is relatively large. Poor, and can not effectively maintain the temperature in the heat collection box, so that it directly affects the overall heat collection efficiency of the heat collector (ie heat gain rate)

specific Embodiment approach

[0024] The second specific implementation mode, as attached figure 1 shown.

[0025] A kind of cover glass of a solar heat collector, comprising a rectangular first plate glass 1, a second plate glass 2 having the same size and shape as the first plate glass 1, and the first plate glass 1 and the second plate glass The periphery of 2 coincides with a sealing member 3 with a certain thickness and a certain width; the first flat glass 1 and the second flat glass 2 are respectively bonded by the sealing member 3 through an adhesive to form a sealed double-layer insulating glass. The double-layer insulating glass is double-layer vacuum glass. On the outer surface 1-1 of the first flat glass 1, also coated with SiO 2 film and TiO 2 Anti-reflective self-cleaning film 5, also coated with the first SiO on its inner surface 1-2 2 AR coating6. It also includes several support members 4; the support members 4 are arranged in the hollow range of the double-layer vacuum glass, and one...

Abstract

The invention discloses case cover glass of a solar thermal collector. The case cover glass is mainly characterized in that: first flat glass (1), second flat glass (2) and a sealing member (3) are comprised, wherein the sealing member (3) is identical with peripheries of the first flat glass (1) and the second flat glass (2) and has certain thickness and width; and the first glass (1) and the second flat glass (2) are adhered by the sealing member (3) through an adhesive to form sealed double-layer hollow glass. The case cover glass of the solar thermal collector, disclosed by the invention, has the characteristics of reasonable structure, durability, capability of remarkably blocking heat conduction and heat radiation to increase temperature of a heated medium, and the like.

Description

technical field [0001] The invention relates to a case cover glass of a solar heat collector, which belongs to the technology of solar energy utilization equipment. Background technique [0002] The solar heat collector is mainly composed of a heat collection box and heat collection tubes arranged in parallel or in series in the heat collection box, and on the daylighting surface of the heat collection box, a cover glass for collecting sunlight is provided, such as household Solar water heaters and solar thermal power collectors, etc. [0003] In order to effectively improve the heat collection efficiency of the heat collection box, while requiring the cover glass to have a strong sunlight transmittance, it is also required that the heat radiation and heat conduction of the hot air in the heat collection box to the outside be minimized as much as possible. Thereby forming the best heat collecting working environment of the heat collecting tube. [0004] Yet the heat collec...
